DESIGN

The capacitor consists of a ceramic disc which is copper

plated on both sides. Connection leads are made of tin

plated copper-clad steel having a diameter of 0.6 mm or

0.8 mm.

The capacitors may be supplied with straight and vertical

kink leads having a lead spacing of 10.0 mm and 12.5 mm.

Encapsulation is made of flame retardant epoxy resin in

accordance with UL 94 V-0.
